Abstract

L'invention concerne un dispositif compact de filtre à particules (5) et de catalyseur à réduction sélective (6) tout en garantissant qu'un temps de réaction satisfaisant pour la formation d'ammoniac à partir d'eau d'urée est réalisé, pour faciliter de cette façon l'incorporation du dispositif sur le véhicule. L'appareil de purification d'échappement est un appareil comprenant, en position intermédiaire du tuyau d'échappement (4), un filtre à particules (5) et un catalyseur à réduction sélective (6) capable d'une réaction sélective de NOx avec de l'ammoniac, même en présence d'oxygène, entre lesquels de l'eau d'urée peut être ajoutée en tant qu'agent réducteur, le filtre à particules (5) étant disposé dans une direction antéropostérieure du véhicule le long d'un cadre de véhicule (10) alors que le catalyseur à réduction sélective (6) est disposé vers l'extérieur dans une direction de largeur de véhicule, à proximité de la partie de bordure côté entrée du filtre à particules (5). L'appareil de purification d'échappement comporte non seulement un canal d'écoulement de communication (9) apte à déplacer vers l'avant le gaz d'échappement (3) émis à partir de la partie de bordure côté sortie du filtre à particules (5) et à l'introduire dans la partie de bordure côté entrée du catalyseur à réduction sélective (6), mais aussi un injecteur d'addition d'eau d'urée (11) (moyen d'addition d'eau d'urée) pour ajouter de l'eau d'urée dans une position intermédiaire du canal d'écoulement de communication (9).
